Trump calls on President Obama to resign in wake of Orlando shooting

"Because our leaders are weak, I said this was going to happen – and it is only going to get worse," Trump said in a statement. "I am trying to save lives and prevent the next terrorist attack. We can't afford to be politically correct anymore."

Trump's campaign said he will address the attacks in a speech he already had scheduled to deliver on Monday addressing national security and responding to criticism from Democratic rival Hillary Clinton.
